IMPROVEMENT IN DEVICE FOR WINDING WATCHES AND CLOCKS.

The Schedule referred to in these Letters Patent and making part of the name.

To all whom it may concern Be it known that I, E. H. HULL, of W'arren, in the county of Trumbull, and State ot Ohio, have invented certain new and useful Improvements in a Method of Winding Watches and Clocks; andIdo hereby declare that the following is afull and complete description of the saine, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is an enlarged view ofthe face of a watch.

Figures 2, 3, and 4 are detached sections.

Like letters of reference refer to like parts in the di'erent views presented.

The nature of this invention relates to a device for winding watches and clocks, by means of a smooth wheel and friction-click, thereby dispensing with the ratchet-wheel and pawl in ordinary use for that purpose.- In g. l, A represents an enlarged view ofthe face of the watch, in which is secured a. wheel, B, by means of a stay, or yoke C, iig. 4, which 'represents a backside view of the wheel.

One side of said wheel is provided with a fiange, D, iig. l, shown also in the transverse view, iig. 2.

E, g. 3, is the click, one end of which is provided with a notch, F, said notch being a little wider than thethigkness of the flange embraced thereby, as shown in g.

The shoulders G of said notch are three-sided, or they may be of any other shape that may be desired.

This wheel and click are placed in the plate of the watch, as shown in fig. l, in which position the notch of the click embraces the flange, as shown in iig. 2.

- H is a spring, whereby one shoulder of the notch is pressed against the outside face of the ange, and the diagonally-opposite one against the inside face of the flange. Now, on turning the wheel in direction ofthe arrow, by inverting the winding-key in the hole b, fig.

4, the flange will move freely in the notch, but cannot be turned in the opposite direction, for the reason that the corners ofthe shoulders are made to press against both sides of the flange by the backward movement given the wheel, which will cause the shoulders .to so hug the flange that the wheel will not turn.

This cramping the flange between the shoulders effectually prevents the unwinding of the watch or clock, and in proportion to the reverse action of the wheel, the stronger will the click cra-mp or lock the flange.

The stern of the click, as it reaches back from the notch, may be so adjusted as to throw the shoulders in the proper position for locking, and which, for clock purposes, may be done, thereby dispensing with the use of a spring, the spring being used only in watches, which, in consequence of their being held in every position, require a spring to retain the click in position for locking.

By the application of this wheel and click, the use of the ratchet-wheel and paw] is dispensed with, it being much cheaper and far more durable, as there are no teeth to wear off or break, as they citen do in the ordinary ratchet-wheel. It also winds easier and without noise, is much stronger, and therefore more durable. It is more simple in structure, and hence easier to make and adjust.

NVhat I claim as my'improvement, and desire to se cure by Letters Patent, is-

The smooth wheel B, provided with a flange, D, as arranged in combination with the friction-click E, when applied to winding watches and clocks in the manner substantially as specified.

E, H. HULL.
